Unable to render a gvis object

[snakonechny]

Hello,

Thank you much for putting together this great package! I'm having some issues with rendering gvis objects in flexdashbaord. Here's a minimal example:

---

title: "Sample"
output:
flexdashboard::flex_dashboard:
orientation: columns

vertical_layout: fill

library(flexdashboard)
library(googleVis)
library(dplyr)

df <- iris %>% group_by(Species) %>% mutate(meanSLength = mean(Sepal.Length))

Column {data-width=650}

Sample column chart in googleVis

renderGvis(

  gvisBarChart(df, "Species", "meanSLength")

)

Above renderGvis I do specify results='asis', message=FALSE, echo=FALSE. Still, I get the following back:

This happens in both the RStudio preview window and the browser.

Any help would be much appreciated!

Thanks!

Yes, googleVIs objects aren't htmlwidgets (http://www.htmlwidgets.org)
which is the standard protocol for JavaScript visualizations within R, and
what we built flexdashboard to interoperate with so I don't think this will
work.

@jjallaire ,
Thanks for a quick response! I tried testing rCharts in flexdashbaord and received a similar error message. I take it these interactive visualizations also aren't supported?

No, we just support htmlwidgets

@snakonechny, using the ggplotly() wrapper from the plotly package on ggplot objects does allow for interactivity in flexdashboard. See: https://paulditterline.shinyapps.io/Louisville_Salaries/

@paulditterline , thanks for the pointer!
